who use and fall in love with the Linux operating system (or call it GNU/Linux) will give the impression that they are smart, kind, naive, and insecure. This should be a good award, because I am also such a person (I seem to boast of myself below ). Linus Torvalds, the father of Linux, is such a kind of temperament. Like a cat, Linus Torvalds is vigorous, powerful, and passionate about freedom. Temperament, mainly temperament, Linus fat beer belly and skill is really not linked.In the Linux Wor

This article organizes the basic process of submitting code to the OpenStack community, as well as some information about the community. If there is reprint, please indicate the source!Let's take a picture to illustrate the general flow of OpenStack code review:The process for submitting code changes to OpenStack is mainly as follows:
Configuring Git and Gerrit Environments
Clone the code of the target project and make changes on the new branch
Commit to a local repo and push it
interrupt command to complete the work you need to do.
Sudo apt-get update 2>/tmp/keymissing;
For key in $ (grep "NO_PUBKEY"/tmp/keymissing | sed "s/. * NO_PUBKEY //"); do
Echo-e "nProcessing key: $ key ";
Gpg -- keyserver subkeys.pgp.net -- recv $ key gpg -- export -- armor $ key | sudo apt-key add -;
Done
A simpler (more automated) Way to get lost PPA keys is to run a small script called launchpad-update when you update your software source.
